25LC080D-I/MS

Overview

The Microchip Technology 25LC080D-I/MS is an 8 Kbit (1024 x 8-bit) Serial Electrically Erasable PROM accessed via a SPI-compatible serial bus. It operates within a voltage range of 2.5 V to 5.5 V and supports a maximum clock frequency of 10 MHz. The device features a 32-byte page size, industrial temperature range (-40°C to +85°C), and TSSOP-8 package.

Feature Summary

• Supports high-speed SPI communication with a maximum clock frequency of 10 MHz.
• Includes programmable block write protection for none, 1/4, 1/2, or all array segments.
• Features built-in power-on/off data protection and a write enable latch mechanism.
• Provides a Hold pin to pause serial transmission without resetting the sequence.

Applications

• Microcontroller system data storage
• Configuration parameter retention
• Calibration value storage

Procurement Notes

Verify the specific suffix 'I/MS' confirms the Industrial temperature grade and MSOP/TSSOP package type. Confirm RoHS compliance status as required by project specifications. Ensure the design accounts for the 32-byte page boundary constraints during write operations to prevent data wrap-around errors.

Selection Notes

Select this component when an 8 Kbit non-volatile memory solution is required with SPI interface compatibility. The Industrial temperature rating suits standard commercial and industrial environments. Verify that the 2.5 V minimum supply voltage aligns with the system's available power rails.

Part Context

This part belongs to the 25XX080C/D family of 8 Kbit Serial EEPROMs from Microchip Technology. The 'D' designation indicates a 32-byte page size, distinguishing it from the 'C' version which uses a 16-byte page. The 'LC' prefix specifies the 2.5 V to 5.5 V operating voltage range.

FAQ

How does the device handle writes that cross a physical page boundary?

If a Page Write command attempts to write across a physical page boundary, the data wraps around to the beginning of the current page instead of being written to the next page.

What is the function of the HOLD pin?

The HOLD pin allows the host to suspend transmission to the device in the middle of a serial sequence without retransmitting the entire sequence, provided the device remains selected.
